Local 44 in West Philly has a nice tap list. Others have mentioned Monk’s, which is top-notch (be sure to check out their bottle menu if you like lambic). Outside the city proper, Teresa’s (Wayne), Capone’s (Norristown) and Pinocchio’s (Media) all have fantastic tap lists. Capone’s, in particular, has bucket list beers on tap pretty much all the time.
